Experimental Study and Mathematical Model to Follow the Colour Changes as Result of Washing Treatments

In this paper, we present the results of an experimental study of the influence of washing treatments of jeans on its colour. It provides a systematic analysis of the changes in colour between two textile substrates: treated and untreated jeans dyed fabrics. The changes of the colour as a result of the washing treatments of the jean fabric were analyzed using the colour strength “K/S” and the colorimetric coordinates (L*, a*, b*) associated with these various treatments. The work also offers a useful modeling to study the influence of different types and parameters of washing treatments on colour changes and colorimetric coordinates, which is important to the textile industry.
